3.9.2.1 Bags and super sacks
Packages for product shipped without reusable openings shall be constructed and properly sealed to make opening or substitution obvious to the purchaser. The packages shall display the company’s name, and employ seals that are destroyed upon opening, or that make resealing unlikely (e.g., serialized tags), or other equivalent tamper-evident measures so that once opened, the tamper-evident feature of the seal on the packaging is unable to be restored or readily duplicated.
3.9.2.2 Drums and small containers
Drums and small containers used for product shall be constructed and properly sealed to make opening or substitution obvious to the purchaser. Openings in the containers shall be sealed with tamper-evident seals and the packages shall display the company’s name. Packages shall employ seals that are destroyed upon opening, or that make resealing unlikely (e.g., ultrasonic seals), or other equivalent tamper-evident measures so that once opened, the tamper-evident feature of the seal is unable to be restored or readily duplicated.
3.9.3 Security requirements for bulk shipments and large reusable containers (totes)
Drinking water treatment chemicals shipped in bulk 1 3 shall be secured during storage and distribution by employing one or more of the following security measures (see Sections 3.9.3.1 , 3.9.3.2, and 3.9.3.3). These requirements are applicable to a single load delivered to one or to multiple locations . 1 4 . This requirement applies to railcar chemical deliveries that are direct to drinking water utilities, or to other end users involved in the addition of the delivered chemical to drinking water, and to truck deliveries whether to a single destination or by milk run deliveries.
3.9.3.1 Tamper-evident seals
Containers used for bulk shipments shall have tamper protection provided at all openings capable of loading or unloading chemicals. Vents shall have tamper protection provided, unless they are protected by construction that makes them incapable of receiving chemicals. Bulk containers may be sealed with a uniquely numbered, nonreusable, tamper-evident seal on each opening in the container. If tamper-evident seals are used, the seals shall remain in place until removed at the point of delivery. Seal numbers shall be recorded and disclosed on shipping documents provided to the purchaser at the time of delivery and kept available for review by the certification body. If tamper-evident seals are used in milk run deliveries, a new seal shall be applied after each partial off-loading and noted in the consignment records after each partial delivery.
3.9.3.2 Chain of custody (COC)
An auditable continuous COC protocol may be used to record secure distribution of product. Maintaining a continuous COC requires that the product is under the continuous control of bonded and designated individuals, that direct access to the product is restricted to those individuals, and that the container is sealed or secured at all times during transport from the place of shipment to the place of delivery. If COC is used, a completed COC record showing continuous and secure custody between the certification holder to the purchaser shall be provided by the transporter to the certification holder and to the purchaser at the time of delivery. The completed COC record returned to the certification holder shall be kept available for review by the certification body.
